How long are the delivery times?If no delivery times are specified for the product in the shop, the product is available for immediate delivery. If products are not in stock, corresponding delivery times are specified. These can be up to 10 weeks. These are maximum delivery times. However, we usually manage to get your parts to you before the maximum delivery time specified. The same generally applies to strut braces. However, if stock strut braces with special gusset plates and/or a powder coating are selected, these are manufactured to customer specifications and/or powder coated. This generally leads to increased delivery times of up to 3 weeks.
-
Why are your delivery times sometimes so long?We produce all parts by hand in-house. Handwork, unlike machine-based mass production in the Far East, takes time. We see ourselves more as a manufacturer than as a mass producer and can therefore guarantee the usual quality of our products.
-
What does SPR actually mean?SPR stands for Street, Performance & Racing and describes what we stand for quite well. Since we can offer solutions for both road vehicles and thoroughbred motorsports, we cover the entire spectrum.

How can I pay?We accept the following payment methods: Credit card Apple Pay Giropay Instant bank transfer with Klarna PayPal Transfer

Thermal insulation / wrapping? Does that make sense?In general, the answer to this question is a clear NO! If adjacent components are exposed to radiant heat, they should be insulated. In special cases, for example when the installation space does not allow it and there is a risk that the whole place will burn down, there is no way around it. Especially for surge-charging manifolds, insulating the manifold has a negative impact on the entire setup, as the accumulated heat increases the exhaust pressure. This reduces the stuffing limit and creates more exhaust back pressure, which leads to poorer scavenging and fresh gas filling. This dramatically increases the exhaust temperature. Our manifolds are based exclusively on the principle of pulse charging. The charger is driven by the exhaust gas pulses and less by the back pressure of the exhaust gas mass. This means that the negative effects of thermal insulation outweigh the positive ones. In addition, insulation places enormous additional strain on the material of the manifold, significantly reducing its service life. Downstream components such as the charger are also subject to greater thermal stress.

Steel flanges? Why don't you use stainless steel?The flanges of our manifolds are made of a steel alloy that is less prone to warping than stainless steel and also has significantly less thermal expansion. This ensures consistent hole and channel spacing. Stainless steel would be counterproductive at this point. The runners are made exclusively from high-temperature-resistant 1.4541 V4A.

How do I install my strut bar?Our strut braces are made exclusively in a one-piece design. This makes installation on the domes more complicated, as the stud bolts of the strut bearing are usually at an angle and the actual distance at the stud bolt end is smaller than at the dome. Therefore, the vehicles must be jacked up on at least one side. This allows the stud bolts to be lowered so far that the strut brace can slide into its final position. Aluminum washers (spacers) are sometimes supplied. These must be installed UNDER the strut, between the dome plate and the dome. If you have any problems or questions please contact us!!

Hood insulation mat: More information on removal.Will there be a disadvantage if I have to remove my hood insulation mat? Since our strut braces require more installation space than the original strut braces on some models, we recommend removing the hood insulation mat. If this is the case for your model, we will point this out under "Installation instructions". Since there is a possibility that it will come into contact with the strut and leave marks, especially on powder-coated struts, the insulation mat should be removed. Below are some questions and answers on this topic: Sounds: We have often received inquiries as to whether the engine noise will become too loud if the insulation mat is removed. To be honest, there is no audible difference. Heat: People often ask whether the mat serves as heat insulation. The mat is just a soundproofing mat. The heat that the mat blocks out is completely negligible. Optics: Without the insulation mat, the hood of the MX5 ND, for example, looks much better and more technical when opened. So here too, there are more advantages than disadvantages. Uninstall: Removing the mat is relatively easy. It is only held in place by plastic clips. These can be easily removed by pulling or levering.

Soundenhancer | MX5 ND / NC : More information.How do I know if my vehicle has a sound enhancer installed? A small plastic hose runs from the intake hose to the splash guard. The sound enhancer is used to transmit the intake noise into the interior. When our strut brace is mounted, the space is more limited and the sound enhancer cannot be installed in its original place. Then there are two options: - ND only - You install our "Soundenhancer Relocation Kit", which you can select from the strut brace. This expands the sound enhancer and moves it to another position. - You remove the sound enhancer. For this you need a plug. This closes the intake pipe at the point where the sound enhancer was installed. The plug is available from various MX5 online shops. E.g. SPR Motorsport or Zymexx. Here you can find a picture of the original Soundenhancer and a comparison of the Soundenhancer with our Relocation Kit.

Powder coating | Without (raw aluminum): What surface does the strut brace have with this selection?The surface of the strut brace is untreated. Since our strut braces are made entirely by hand, traces of manufacturing may still be present. Small impressions, deposits from welding and marks from the bending process must be expected. We take great care to ensure the integrity of the surface at every step of the process. Unfortunately, small manufacturing marks sometimes cannot be avoided. The finished strut brace is also finished to ensure that you get the best possible surface. However, some manufacturing marks may still be visible. For a perfect surface and the best look, we recommend choosing a powder coating. However, if you are primarily concerned with the function of the strut brace or if you want to have your brace painted / powder-coated in a special color that we do not offer, then the option "Without (raw aluminum)" is the right choice for you.
